Black obsidian is a very powerful and protective Stone. It grounds the soul and spiritual forces into the physical plane, bringing them under the direction of the conscious will. Self-control is increased with this stone. Also, this stone has a good action to cut ties, to break negative attachments to people with whom you have been close.
